ADOLPH ARGO, OF SOHLOSS OHEMNITZ, SAXONY, GERMANY.

MACHINE FOR'MANUFACTURING WIRE HEDDLES.

SPECIFICATION forming part of Letters Patent No. 233,593, dated October 26, 1880.

Application filed September 13, 1880.

To all whom "it may concern Be it known that I, ADOLPH ARGO, of Schloss Ohemnitz, in the Kingdom of Saxony, in the German Empire, have invented certain new and useful Improvements in Machines to be used in the Manufacture of Wire Heddles for Looms, of which the following is a specification.

Heddles for looms have frequently been formed by twisting together two wires or two portions of the same wire, leaving a small eye at the middle for the passage of the thread, and an eye at one or both ends for securing the heddle in the heddle-frame.

The object of my invention is to make such twisted wire heddles more compact, solid, and stiff between the eyes; and to this end my invention consists in a machine of novel construction to be employed in rolling the portions of the twisted heddles upon each side of the central thread-eye, so as to give such portions the appearance of a single cylindric wire.

In the accompanying drawings, Figure 1 represents an end view of a machine embodying my improvements, and Fig. 2 represents a central longitudinal section of such machine.

Similar letters of reference designate corresponding parts in both figures.

The heddles are first formed by twisting together two wires or two portions of a single wire through the entire length of the heddle, save at the thread or middle eye and the end eyes, and the portions between the eyes are then subjected to arolling pressure, ora rolling action while under pressure, whereby the beddles are made stronger, more solid, and stifi.

The machine here represented may be very conveniently employed for rolling the heddles, and I will now proceed to give a detailed description thereof.

A and B designate, respectively, the lower and'upper plates, between which the heddles are placed and rolled. As here represented, the surfaces of said plates are formed by attachin g to each plate removable faces or faceplates a, secured in place by means of bolts b, and composed of hardened steel or other suitable hard material. As clearly shown in Fig. 1, each pair of faceplates a is slightly sepa- (No model.)

rated at the center, so as to form opposite channels 0, which receive the central or thread eyes of the heddles, and preserve them from injury while the portions upon each side thereof are rolled. The lower plate, A, has upon its under side a dovetailed recess or groove, d, which receives a correspondingly dovetailed projection or slide upon a base or bed, 0. A longitudinal or reciprocating movement may be imparted to the lower plate, A, by means of a pinion, D, which engages with a rack, E, upon said plate, and which is fixed to a shaft, F, to which rotary motion may be imparted by a crank, G, or other suitable means.

H designates a frame secured rigidly to the base or bed 0. The upper plate, B, is suspended from the frame H by means of a screw, I, which has an eye-connection with the said plate, and fits loosely in a socket in the frame H. Upon the screw I above the frame are applied nuts e c, which provide for raising or lowering the plate B relatively to the plate A, and securing it when so raised or lowered.

J designates screws, of which four are here shown, each fittingin a screw-threaded socket in the frame H, and bearing upon the top of the plate B at one side, the four screws hearing upon the top surface of the plate at the four sides. To each of the screws J is applied a jam-nut, f, to prevent it from turning when once adjusted, and at the upper end of each screw is a cylindric smooth portion, g, and a square or polygonal head, h, to which a wrench may be applied.

K designates a frame or plate having in it holes or sockets, which receive the cylindric portions 9 of the screws J, and provided with set-screws t, which clamp upon the screws and still further prevent them from accidental turning.

The vertical position of the plate B may be varied and fixed by means of the screw I and nutse e, and by means of the several screws, J the said plate may be adjusted to bring its lower face parallel with that of the plate A, or at a slight incline thereto, so that the opening between the plates will be slightly wider at the side of the machine at which the heddles are introduced than at the other side, at which the heddles are delivered, so that the heddles will be subjected to a constantly increasing pressure as they pass through the machine. 7

The screws I and J having been adjusted to suit the size of the heddles to be rolled, the heddles are introduced one by one between the plates A and B, and upon turning the crank Gr they are carried through the machine, and the portions upon each side of the center or thread eye subjected to such a rolling pressure that when the heddles are delivered the said portions present the form of a single solid wire.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in a machine for rolling wire heddles, of lower and upper plates, between which the heddles are to be placed,and which have spaces for the heddle-eyes, mechanism for moving the lower plate longitudinally, and devices for adjusting the upper plate vertically and at an inclination relatively to the lower plate, substantially as specified.

2. The combination of the lower plate, A, having a space for the heddle-eyes, and mechanism for moving it longitudinally, the upper plate, B, having a corresponding space, and the adjusting-screws I and J, substantially as and for the purpose specified.

3. The combination, with the lower plate, A, the rack E, pinion D, shaft F, and crank G, of the upper plate, B, the frame H, the screw 1, with its nuts 0, the screws J, with jam-nuts f, the frame or plate K, and setscrews 1', the plates being adapted to receive the hcddle-eyes, all substantially as specified.

In testimony whereof I have hereunto set my hand this 24th day of July, 1880, in the presence of two subscribing witnesses.

ADOLPH ARGO.
